A window ventilator such as described is,

, very simple and cheap toconstruct and may ;;be adjusted very quicklyand, allows t thorough ventilation of a room without the detrimentaleffect of a straight passage or openin".

The member 3 is herein shown as having the plate portion at arranged ina horizontal position but it must be understood that this plate orbottom portion may be arranged at an incline from the surface of thesash it so desired.

lVhat I claim as my invention is 1. In a window ventilator, thecombination with the sash having an orifice therethrough, of a sheetmetal member secured to the inner side of the sash having a horizontalplate projecting inwardly and extending the -full length of the orifice,said menr ber having rigid end walls, and a movable plate adapted torest upon the inwardly extending plate member and to rise upwardlytherefrom between the ends and adapted to be held in adjusted positions.

2. In a window ventilator, the combination with the sash rail having anorifice therethrough, of a sheet metal member secured to the inner faceof said sash and having a plate portion extending longitudinally of theorifice and projecting inwardly from the sash and provided withlongitudinal grooves in its upper face and having end walls risingtherefrom, said end walls having notched recesses, an adjustable platemember adapted to rest in the grooves in the longitudinal horizontalplate and adapted to engage the notches in said end plates and forming aballie.

3. In a window ventilator, the combination with the sash rail having anorifice therethrough, of a member secured to the sash and extendinglongitudinally of the orifice and having upturned ends, said memberhaving a longitudinal beveled surface adjacent to the face of the sashand grooves extending longitudinally parallel. with said sash, the endportions of said member each having a notch adjacentto the sash formedwith an inwardly beveled edge and notches in the upwardly extendingportions, and an adjustable plate member adapted to extend between saidend portions and having a beveled lower edge adapted to engage thelongitudinal grooves in the aforesaid member, and projecting endportions adapted to engage the notches in said end plates.

Signed at the city of Toronto, Canada, this 18th day of May 19l5.
